Getting back to the plastic bag debate, when I was growing up (over 20 years ago now....) supermarkets in my town has cordened off areas with boxs for you to pack up your shopping. I never seen anything like this now. Maybe the occasional banana box at the end of a till, but nothing of the scale that it was. It strikes me that they now either recycle the cardboard themselves or bin it.
I would like to see a return to the days of cardboard box areas which my stop some of the overuse of dreadful plastic bags.
